-0.6
A power system has two synchronous generators. The Governor-turbine characteristics corresponding to the generators are
P1 = 50(50 – f), P2 = 100 (51 – f)
Where f denotes the system frequency in Hz, and P1 and P2 are, respectively, the power outputs (in MW) of turbines 1 and 2. assuming the generators and transmission network to be lossless, the system frequency for a total load of 400 MW is
A
47.5 Hz
B
48.0 Hz
C
48.5 Hz
D
49.0 Hz
